## Description
|
|
<section id='description'>
|
|
The previous challenges covered how to use some of the animation properties and the <code>@keyframes</code> rule. Another animation property is the <code>animation-iteration-count</code>, which allows you to control how many times you would like to loop through the animation. Here's an example:
|
|
<code>animation-iteration-count: 3;</code>
|
|
In this case the animation will stop after running 3 times, but it's possible to make the animation run continuously by setting that value to infinite.

|
|
## Instructions
|
|
<section id='instructions'>
|
|
To keep the ball bouncing on the right on a continuous loop, change the <code>animation-iteration-count</code> property to infinite.

- text: The <code>animation-iteration-count</code> property should have a value of infinite.
|
|
testString: assert($('#ball').css('animation-iteration-count') == 'infinite', 'The <code>animation-iteration-count</code> property should have a value of infinite.');
